lsnodecanisterstats
The lsnodecanisterstats command displays the most recent values of all node canister statistics, and displays all node canister statistics for a particular canister. This command also can be used to display a history of values for a given subset of available statistics.
Syntax
>>- lsnodecanisterstats -- --+-----------------------+-- -------> '- -delim -- delimiter -' >--+-----------------------------------+-- ---------------------> '- -filtervalue -- attribute=value -' >--+-----------------+-- ---------------------------------------> '- -filtervalue? -' >--+------------------------------------------------------+---->< '-+- -history -- stat_list -+-+- node_canister_id --+-' '- ------------------------' '- nodecanister_name -'
Parameters
- -delim delimiter
- (Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
- -history stat_list
- (Optional) Provides the most recent node canister statistical values, specific canister statistical values, or historical data for any canister.
- nodecanister_id | nodecanister_name
- (Optional) Identifies the node canister for which you want to request statistics.
Description
This
command returns a concise list or a detailed view of node canisters
that are part of the clustered system. Table 1 provides the
possible values that are applicable to the attributes that are displayed
as data in the output views.
Attribute | Value |
---|---|
nodecanister_id | The ID of the node canister. |
nodecanister_name | The name of the node canister. |
stat_current | The current value of the statistic field. |
stat_list | The system history of the reported statistics. |
stat_name | The name of the statistic field. |
stat_peak | The peak value of the statistic field in the last five minutes. |
stat_peak_time | The time that the peak occurred. |
sample_time | The time of the sample occurrence. |
stat_value | The statistical value at the epoch interval. |
Note: Filtering is supported on nodecanister_id, nodecanister_name,
and stat_name fields using the concise
view.
